IMPROVED ELEVATED RAI LwAY Specification forming part of Letters PatentNo. 89,541, dated April 27, 1869.

To all whom it may concern:

Be it known that I, Brennan MONTGOM- ERY, of the city, county, and Stateof New York, have invented a new and useful Improvement in ElevatedRailroads and Railroad-Bridges; and I do hereby declare the following tobe a full, and exact description thereof, reference being had to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a plan or top view of my improved elevated railroad with acar-truck thereon; Fig. 2, an end view or transverse section thereof,and Fig. 3 a cross-section of the supporting-column in the line was ofFig. 2.

Similar letters indicate like parts in each of the figures.

In elevated railways supported upon single columns, as illustrated inFig. 2 of the drawings, it is evident that each column becomes a longlever, having its fulcrum and shorter arm within the base, so that theleast lateral pressure at its upper end, or even a slight swayingmovement in a train of cars supported thereon, must exert a very severestrain upon its joint with the base. Hence it becomes highly importantnot only to impart great strength and solidity to the joint of thecolumn with its base, but also to prevent all oscillation of the cars inpassing over the columns. The increased danger of disastrous resultsfrom the running off the track of a train of cars also increases theimportance of providing some sure effective guard against such anaccident.

The object of my invention is to avoid these dangers, and to prevent aswaying movement of cars running upon elevated railways or over bridges,and to so confine the cars upon the track as to prevent any accidentaldisplacement thereof from the rails.

The nature of my invention consists in combining, with the ends of thecross-beams, bars, or ties of an elevated railroad or bridge, verticalstandards, carrying horizontal guardrails, running longitudinallyparallel to the track, at such height above the same as may be founddesirable, to engage small frictionwheels projecting from the sides ofthe cartrucks.

In the accompanying drawings I have illustrated an elevated railroadconstructed of my corrugated metal beams, rails, and columns, combined,united, and secured, as has been heretofore fully described in LettersPatent of the United States granted to me therefor.

Instead, however, of cutting ofi the transverse beams or cross-ties Asupporting the track 13 B of the railroad at the outside of the track,as has heretofore been customary, I bend up the ends of these cross-tiesA and prolong them into upright standards 0 G, as shown in Fig. 2. Tothe inner side of these standards 0 O, on each side of the track,I'secure, horizontally, beams or bars D, by preference corrugated, so asto form a continuous side of guard-rail parallel to the track-rails.Small friction wheels or rollers E E are secured to the outer sides ofthe cars or trucks F, so as to bear lightly against the side rails D D,and thus steady and support the trucks laterally, so as to prevent aswinging or swaying movement thereof from side to side, and confine themto the track.

Instead of curving the ends of the cross-tie beams A to form theuprights O to sustain the lateral guard-rails D, these uprights may beformed of independent bent pieces, whose inner ends shall rest upon andbe secured to the straight ends of the tie-beams, and thence curveupward, so as to form standards C, as required.

I propose in some cases to combine with the side friction-rollers uponthe trucks F of the cars and engines to be run upon the guarded track,springs to be interposed between the rollers and the truck, so as toforce the rollcrs, with an elastic pressure, against the guardrails D,and allow a very slight easy movement of the truck, preferable, perhaps,to a inore rigid confinement thereof.

By means of these friction-rollers, in combination with the guard-rails,the trucks are stayed and confined laterally, without the leastinterference with their proper direct forward movement upon the track,and hence all danger of running off the track is removed, while adangerous vibration of the structure is at the same time prevented.

Having thus fully described my invention, I claim therein as new anddesire to secure by Letters Patent- 1. Standards 0 O, in combinationwith the cross-tie beams A A and continuous lateral guard-rails D D ofan elevated railway or railway-bridge, substantially as herein setforth.

2. Also, friction-wheels E E, when combined with a car or car-truck, F,running between the lateral guard-rails D D of an elevated railroad,substantially in the manner herein set forth.

Witness my hand the 18th day of February, 1869.

R. MONTGOMERY.
